%X This study focused to determine the bacteriological quality of different
commonly used water sources, including boreholes, hand pumps, surface water,
household containers, dug well and cement reservoirs in Pelengana commune, in
Mali with special reference to the internally displaced people camps. Four
hundred and eight water samples were collected from different sites and
sources, from July 2016 to June 2017. Water samples were examined for total
coliform, fecal coliform and fecal enterococci counts using the most probable
number method. Also, samples were investigated for the presence of enteric
bacteria isolated, namely</span><i><span style=\"font-family:Verdana;\"> Escherichia
coli</span></i><span style=\"font-family:Verdana;\">, </span><i><span style=\"font-family:Verdana;\">Enterococcus fecalis</span></i><span style=\"font-family:Verdana;\">, </span><i><span style=\"font-family:Verdana;\">Bacillus</span></i><span style=\"font-family:Verdana;\">, </span><i><span style=\"font-family:Verdana;\">Citrobacter</span></i><span style=\"font-family:Verdana;\"> and </span><i><span style=\"font-family:Verdana;\">Enterobacter</span></i><span style=\"font-family:Verdana;\">.
Results revealed that the three indicators bacteria (Total Coliform (48.7%),
Fecal Coliform (100%), and Fecal enterococci (37.01%)) were found above
permissible limit for drinking water. The highest number of the indicators
bacteria found was</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\">1800</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">TC/100ml water. Enteric bacteria isolated were </span><i><span style=\"font-family:Verdana;\">Escherichia coli </span></i><span style=\"font-family:Verdana;\">(25.7%), </span><i><span style=\"font-family:Verdana;\">Enterococcus
fecalis</span></i><span style=\"font-family:Verdana;\"> (21.91%), </span><i><span style=\"font-family:Verdana;\">Bacillus</span></i><span style=\"font-family:Verdana;\"> (16.72%), </span><i><span style=\"font-family:Verdana;\">Enterobacter </span></i><span style=\"font-family:Verdana;\">(4.56%) and </span><i><span style=\"font-family:Verdana;\">Citrobacter</span></i><span style=\"font-family:Verdana;\"> (3.91%). The most
contaminated water source was surface water (15.28%) followed by household
containers (13.65%), boreholes (8.75%), cement reservoirs
